Respuesta :
X = the amount of orange juice that still has to be mixed
If it says that the total of the juice will be 200 liters, then (200-x) = the amount of grapefruit juice that still needs to be mixed.
The grapefruit juice amount would be: 200 - 80 = 120 liters
If it says that the total of the juice will be 200 liters, then (200-x) = the amount of grapefruit juice that still needs to be mixed.
The grapefruit juice amount would be: 200 - 80 = 120 liters
Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
Cost of grapefruit per liter = 32
Cost of orange juice per liter= 42
Total quantity of mixture = 200 liters
Let the quantity of orange juice be x
So, the quantity of grapefruit juice be 200-x
So, the total cost of the grapefruit juice used will be
[tex]0.32(200-x)[/tex]
According to question,
[tex]0.32(200-x)+0.42x=200\times 0.36\\\\64-0.32x+0.42x=72\\\\0.42x-0.32x=72-64\\\\0.1x=8\\\\x=80\\\\\text{ So, the amount of grapefruit juice will be }=200-80=120[/tex]
Hence, Second option is correct.
